Overview

The Keling KL-LED-DTR78 is a double-dome ceiling-mounted LED shadowless operating lamp with integrated camera system, designed for hospitals and surgical centers requiring high-performance illumination combined with intraoperative video documentation. Each primary dome delivers 160,000 lux at 1 m using OSRAM LED components. The titanium-alloy balance arm ensures stable, drift-free positioning throughout lengthy procedures — a critical feature in high-precision surgery where lamp movement between adjustments must be eliminated.

The KL-LED-DTR78 incorporates a computer-programmed optical arrangement for high shadowless rate, and high thermal conductivity heat dissipation technology to maintain a low temperature rise within the fixture and at the operative site. Optical PC lenses on each LED element provide anti-glare performance for the surgical team. The heat-to-light ratio is ≤3.2 mW/m²lx, limiting radiant heat exposure during long procedures.

The KL-LED-DTR78 offers a comprehensive set of illumination modes: an Endo mode at 15,000 lux for minimally invasive procedures, a green light mode (R11≥97) specifically engineered for cardiac and neurosurgery disciplines requiring high green color rendering, and continuously adjustable color temperature from 3,000 K to 6,700 K. Illumination automatic compensation activates when occlusion is detected, maintaining consistent brightness at the operative field. The RI index function is specifically designed for high color-rendering tasks including deep and difficult incisions where tissue color discrimination is most critical.

Frequently asked questions

What is the Keling KL-LED-DTR78 used for?

The Keling KL-LED-DTR78 is a double-dome ceiling-mounted LED shadowless operating lamp with an integrated camera system, used in hospital operating rooms for high-intensity illumination combined with intraoperative video recording or telemedicine. It is particularly suited to cardiac surgery and neurosurgery via its green light mode (R11≥97), deep procedures via its 150 cm depth of illumination, and minimally invasive procedures via its Endo mode at 15,000 lux.

What LED brand does the KL-LED-DTR78 use, and how many LEDs are fitted?

The KL-LED-DTR78 uses OSRAM LED components. Dome 1 contains 84 LEDs and dome 2 contains 144 LEDs, both rated for an average service life of 50,000 hours. Both domes deliver 160,000 lux at 1 m working distance with a heat-to-light ratio of ≤3.2 mW/m²lx.

What is the titanium-alloy balance arm feature on the KL-LED-DTR78?

The KL-LED-DTR78 suspension arm is constructed from titanium alloy and engineered for no-drift operation.
